THE PRESENT PERFECT 1

                                                                    + ed   (regular verbs)

Has/have + past participle                       

                                                                    3rd form (irregular verbs)

 

USE:

• No TIME INDICATOR (like yesterday) in the sentence, but the action is finished

eg: I have bought a new car!

      She has been to Africa twice.

 

• When one of these words is in the sentence: just/ already/ lately/ recently/ yet/ ever/ never

eg: I have already done my homework.

      She hasn’t seen her teacher yet.

 

• When something started some time ago and is still going on or true

eg. I have lived in Katwijk for 7 years (I still live here)

      She has played tennis since 2013(and still does)

 

Has and Have are auxiliaries here, so you have to start with them in a question (Have you already seen him?) and in a negative sentence you put NOT after have or has. (We haven’t written stories yet)
